反応条件: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a suspension of 2-chloro-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (500 mg) and 2,2-dimethylpentanol (3.8 mL) at 50° C. was added sodium hydride (396 mg, 60% dispersion) in portions. To the resultant viscous foam was added a further portion of 2,2-dimethylpentanol (1.5 mL). The reaction was stirred at 50° C. for 72 h. The reaction mixture was cooled then carefully quenched with water (10 mL) and extracted with EtOAc (3×25 mL). The organics were combined, washed with brine (30 mL), dried over MgSO4, filtered and concentrated in vacuo to give a yellow oil. This was azeotroped with toluene (×3) and the resulting viscous yellow oil was purified by C18 reverse phase chromatography (ISCO) using water (0.1% formic acid)-acetonitrile (0.05% formic acid) as eluent (30-80%) to afford the title compound as a brown solid (372 mg). The reaction mixture was cooled then carefully quenched with water (10 mL) extracted with EtOAc (3×25 mL) washed with brine (30 mL) dried over MgSO4 filtered concentrated in vacuo to give a yellow oil This was azeotroped with toluene (×3) the resulting viscous yellow oil was purified by C18 reverse phase chromatography (ISCO)
